It did feel at the time that they were trying to pair the two up as there seemed to be chemistry between them and in the end he came good (so more likely Alex would let him closer) rather than the cheapo Lex copy it looked like they were going to go for during season 1.
Alex has said herself to Kara that it's been a while since she's dated proper, implying boyfriends in the past, prior to her newfound preference for women. Maybe she's bi, either way not a big deal, just seems a bit forced they're trying to get her and the cop closer than friends/colleagues.
Max seems to have just been dropped with not even a mention in season 2. Can't remember him being bumped off at the end of season 1, so an abrupt change to make way for the Luthors? A bit like the change of location for the DEA where Supergirl said at the start of season 2 what we'd all be wondering "it's been here the whole time and only now you're letting me know?". In other words, why have her always fly out to the old desert location if this one was nearer.
